From our favorite relabeler International Servicemaster
Chinese made 12AX7 selected for ECC803S qualities
We are just selling them as a 12AX7A
This is early production stock (before the fancy new brands).
Very nice section to section balance (3%)
With ICC Servicemaster, you never knew what you were getting.
It could be then current production or some old vintage gem.
